Pardon my ignorance. I still don't really grasp the meaning the words.For example:"Hollywood's 'perception' of the tastes of the American public is jaded."vs."Hollywood's 'perspective' of the tastes of the American public is jaded."

Often there is such a minor difference between the two that it is difficult to decide which to use. However, often it doesn't matter which you use for that very reason!_________________"Inside every old person is a young person wondering what happened."
Terry Pratchett
